Charter of the United Nations
Introduction

The Charter of the United Nations was signed on 26 June 1945,
in San Francisco, at the conclusion of the United Nations Conference
on International Organization, and came into force on 24 October
1945. The Statute of the International Court of Justice is an
integral part of the Charter.

Amendments to Articles 23, 27 and 61 of the Charter were adopted
by the General Assembly on 17 December 1963 and came into force
on 31 August 1965. A further amendment to Article 61 was adopted
by the General Assembly on 20 December 1971, and came into force
0n 24 September 1973. An amendment to Article 109, adopted by
the General Assebmly on 20 December 1965, came into force on 12
June 1968.

The amendment to Article 23 enlarges the membership of the
Security Council from eleven to fifteen. The amended Article 27
provides that decisions of the Security Council on procedural
matters shall be made by an affirmative vote of nine members (formerly
seven) and on all other matters by an affirmative vote of nine
members (formerly seven), including the concurring votes of the
five permanent members of the Security Council.

The amendment to Article 61, which entered into force on 31
August 1965, enlarged the membership of the Economic and Social
Council from eighteen to twenty-seven. The subsequent amendment
to that Article, which entered into force on 24 September 1973,
further increased the membership of the Council from twenty-seven
to fifty-four.

The amendment to Article 109, which relates to the first paragraph
of that Article, provides that a General Conference of Member
States for the purpose of reviewing the Charter may be held at
a date and place to be fixed by a two-thirds vote of the members
of the General Assmbly and by a vote of any nine members (formerly
seven) of the Security Council. Paragraph 3 of Article 109, which
deals with the consideration of a possible review conference during
the tenth regular session of the General Assembly, has been retained
in its original form in its reference to a "vote, of any
seven members of the Security Council", the paragraph having
been acted upon in 1955 by the General Assembly, at its tenth
regular session, and by the Security Council.
